NIH Links Forever Chemicals to Aggressive Breast Cancer
NIH study ties PFOA and PFOS to higher rates of aggressive breast cancer.
In brief
NIH study ties PFOA and PFOS to higher rates of aggressive breast cancer. NIH research shows women with high blood levels of PFOA have 67% higher risk of estrogen receptor-negative breast cancer compared to low exposure groups. Originally reported by Dallas Express.
NIH Study Finds Link
NIH researchers found women in highest PFOA exposure groups had 67% higher estimated rates of estrogen receptor-negative breast cancer.
“The results appeared two days after 3m announced a $7.35 billion agreement concerning pfas-related personal-injury claims.”
Study Methodology
The analysis used the NIH Sister Study with 50,884 women from 2003 to 2009, measuring 17 pfas chemicals in blood.
Exposure Levels
Women with highest exposure had 93% higher rates of estrogen receptor-negative breast cancer for PFOS compared to lowest exposure groups.
3M Settlement
3M agreed to a $7.35 billion settlement for pfas-related personal-injury claims but did not list breast cancer as covered.
Texas Legal Action
Texas sued 3M and DuPont-related businesses in 2024 over alleged misleading marketing of pfas-containing consumer products.
Consumer Advice
EPA sets drinking-water limits of 4 parts per trillion for pfoa and pfos; residents can check water testing and use certified filters.
The headline
NIH research shows women with high blood levels of PFOA have 67% higher risk of estrogen receptor-negative breast cancer compared to low exposure groups.
